The blockchain is immutable, but like any council, the witnesses can still remove content like CP if it does appears on Steemit.

There seems to be a contradiction in something that is immutable and yet can still have content removed. If the witnesses can remove it then they can change the blockchain and it's not immutable. If the witnesses can't actually change the blockchain then they can never truly remove anything they can only try and hide it.
There is new technology coming to the blockchain that does away with immutability and does allow block changes. IBM is looking at it I believe?? That is very scary!!
How do you consider it to be true?
Can the blockchain be changed or not? This isn't some sort of quantum super state.
"Can you remove content from the blockchain?"
Without complete knowledge of the inner workings I will hazard saying yes from what I understand. I believe that a consensus of the top 20 witnesses could push through an altered blockchain but I could be wrong.
Let's assume they can for argument's sake. That would mean that the blockchain isn't immutable since it can be changed in that scenario. This relies on the blockchain being defined as the current live consensus version.
You've added a restriction that it must be changeable by an individual. No such restriction should be expected when calling something immutable. Immutable as a term on it's own in binary, it is changeable or not. I also specifically stated that it relies on the definition of the blockchain being the currently accepted consensus. That does not include backups and rogue chains.
